Definitions

  • the invention relates to a device and a method for controlling brushless, in particular 4-strand DC motors.
  • the rotating fields required for converting electrical into mechanical energy by means of electric motors can be generated mechanically (brushes in connection with collectors attached to the rotor) or electronically using semiconductor switches.
  • a brushless DC motor is known from US Pat. No. 4,484,115, the stator of which is wound with a 7-strand winding in star or ring connection.
  • the rotor of the DC motor is covered with permanent magnets.
  • the current required to generate a rotating field is controlled with the aid of semiconductor switches, for the control of which a position sensor which detects the rotor position is used. Two semiconductor switches are assigned to each winding phase to enable bipolar operation.
  • the brushless direct current motor described in the US patent has the disadvantage that a pair of complementary transistors is required for its control per line. This is a complex and costly solution.
  • the brushless DC motor according to DE-PS 33 01 801 has the disadvantage that the stator winding strands are connected in a star connection. With this switching of the stator winding, the stator cannot be wound fully automatically, and soldering work is also required on the winding heads. In addition, with such a stator winding, the end windings become quite large in the axial direction, which leads to additional electrical losses.
  • the object of the invention is to provide an inexpensive and largely automatically manufactured brushless DC motor and a method for its control. This object is achieved by a DC motor with the combination of features of the first device claim and by a method with the features of the method claims.
  • the brushless DC motor according to the invention has the advantage that only four semiconductor switches are required to control its four strands. Another advantage is that the stator winding is connected in a ring circuit. In this way, the stator can be wound fully automatically. Soldering on the winding heads are not required and the entire winding is shorter in the axial direction than conventional stator windings. Another advantage is the fact that the DC motor can be controlled with several switching sequences.
  • Fig. 1 shows the basic structure of a control circuit for a 4-strand brushless DC motor, the stator winding is connected in a ring circuit. 1 contains all the elements that belong to the DC motor and not to the control circuit.
  • 11 denotes a rotor covered with permanent magnetic material, 12, 13, 14 and 15 identify the four strands of the stator.
  • 16 and 17 denote two magnetic field sensors which detect the position of the rotor 11. The two sensors 16 and 17 are connected to a commutation circuit 18.
  • the output of the commutation circuit 18 is connected to a driver circuit 19 via lines labeled 20.
  • 21 denotes a switch A+, 22 a switch B ⁇ , 23 a switch C+ and 24 a switch D ⁇ .
  • the two switches A+ and C+ connect points A and C on the motor to the supply voltage.
  • the switches B ⁇ and D ⁇ connect the points B and D to the ground.
  • 25 a connection for the supply voltage is designated, with 26 a smoothing capacitor.
  • FIG. 2 serves to explain the switching sequence of the arrangement according to FIG. 1 with simple commutation.
  • the circle labeled 30 schematically identifies a stator of a brushless DC motor wound with four winding strands connected in a ring circuit.
  • the points denoted by A, B, C and D correspond to the points A, B, C and D in FIG. 1.
  • the arrows marked 31 in the circumferential direction show the direction of current flow in the individual strands in the respective switching state of the semiconductor switches.
  • 32 denotes a flow vector resulting from this current distribution.
  • a filled connection point A, B, C or D stands for the connection of this point with the supply voltage or with the ground.
  • Second step switches A+ and D ⁇ are closed, the flow vector rotates 90 o further.
  • Fourth step switches C+ and B ⁇ are closed, switches A+ and D ⁇ open.
  • the first step is started again. It can be seen from the flow arrows in FIG. 2, designated 32, that a switching field is generated by this switching sequence, which drives the rotor of the machine.
  • the flow pattern shown here refers to a two-pole machine in which an electrical angle of 2 pi corresponds to a machine angle of 2 pi. With a higher number of pole pairs and the same control sequence, the rotor rotates by an electrical angle of 2 Pi or by a spatial angle of 2 Pi / p with p equal to the number of poles of the motor.
  • FIG. 1 The arrangement according to FIG. 1 can, however, be controlled in a different way.
  • a Switching sequence hereinafter referred to as double commutation, is described with the aid of FIG. 3.
  • the number of the schematically represented motors in the top line of FIG. 3 is twice as large as in FIG. 2.
  • the designations of the connections, the current flow in the individual lines and the resulting flow vector are as in FIG. 2.
  • First step switches A+ and B ⁇ closed, switches C+ and D ⁇ open
  • second step switches A+, B ⁇ and D ⁇ closed, switch C+ open
  • third step switches A+ and D ⁇ closed, switches C+ and B ⁇ open
  • fourth step switches A+, C+ and D ⁇ closed, switch B ⁇ open
  • fifth step switches C+ and D ⁇ closed, switches A+ and B ⁇ open
  • sixth step switches C+, B ⁇ and D ⁇ closed, switch A+ open
  • seventh step switches C+ and B ⁇ closed, switches A+ and D ⁇ open
  • Eighth step switches A+, C+ and B ⁇ closed, switch D ⁇ open.
